Abstract

A parted annular piston sealing ring and a method for manufacture thereof wherein an inwardly facing ring surface adapted to be engaged by an expander-spring for expanding the ring into sealing engagement with a cylinder wall is hardened in a zone immediately adjacent the parted ring tips. Hardening of the spring-engaging surface at the ring tips reduces wear and embedment between the ring and spring in the region of the ring gap while permitting resilient flexure of the ring in regions removed from the ring gap to follow surface variations in a cylinder wall.
